RESUMEN

Evidence indicates that patterns of biological reactivity underlie different forms of aggression, but greater precision is needed in research targeting biopsychosocial processes that underlie such differences. This study investigated how sympathetic and parasympathetic nervous system (SNS and PNS) responses to social stress were associated with multiple forms of aggression in an ethnically-diverse sample of young adult females; it further examined whether early life exposure to family conflict moderated these relationships. In the context of high levels of family conflict history, greater SNS activation during a social conflict task was associated with more direct proactive aggression and increasing RSA was associated with more direct reactive aggression. Greater SNS activation during the task was associated with more direct reactive aggression regardless of family conflict history. Our findings affirm the need to capture the contributions of multiple physiological systems simultaneously and the importance of considering family history in the study of aggression.

RESUMEN

BACKGROUND: A Dissociative Subtype of Posttraumatic Stress Disorder (PTSD) was added to the DSM-5, but little is known about this symptom pattern in young children exposed to trauma. Tailoring treatment to traumatized young children requires understanding the different patterns of trauma-related symptomatology and important correlates. The current study tested the hypothesis that type and number of child traumatic events, caregiver trauma exposure, and caregiver symptomatology would predict whether traumatized young children presented with PTSD, PTSD with clinical dissociation, or non-clinical trauma symptoms. METHODS: A multinomial regression was conducted using data collected from an ethnically and economically diverse sample of 297 trauma-exposed children between the ages of 3 and 6 and their caregivers. Based on parent-report on a well-validated measure of trauma symptoms, children were categorized into three groups: non-clinical (n = 128), PTSD only (n = 104), or PTSD with dissociation (PTSD-DISS; n = 65). Predictors included trauma exposure, parent trauma symptoms, and child sex. RESULTS: Girls were twice more likely than boys to be in the PTSD-DISS group; sexually abused children were almost three times as likely to be in the PTSD-DISS group; and, for every unit increase in parent avoidance symptoms or number of traumatic events, the odds of being in the PTSD-DISS group increased significantly. LIMITATIONS: Given the cross-sectional study design, conclusions cannot be drawn regarding causality. Measures were completed by a single reporter. CONCLUSIONS: Findings suggest that subgroups of children may be especially vulnerable to comorbid PTSD and dissociation. Implications for treatment are discussed.
